I have a strange problem on an imported cad model (ArchiCAD to C4D). The texture is in cubic protection mode. If i add a tile surface it seems to be correct but in the render the displacmentmap shows on some corners "triangles" (see 04.jpg).
Is there a way to remove them? (uvw projection doesnt work either but thats due to the import from my cad)
thx for your help
